Concatenation of Space-Time Block Codes and Turbo Trellis Coded Modulation (ST-TTCM) Over Rician Fading Channels With Imperfect Phase Reference

In this paper, the performance of Space-Time - Turbo Trellis Coded Modulation (ST-TTCM) is evaluated over Rician fading channels with imperfect phase reference. For high data transmission over wireless fading channels, Space-Time Block Codes provide the maximal possible diversity advantage for multiple decoding algorithms. The combined effects of fading channel and non-ideal coherent receiver on the phase of the received amplitude and of a noisy carrier reference are considered, each modeled by Rician and Tikhonov distributions respectively. Here, we investigate Space Time-Turbo Trellis Coded Modulation (ST-TTCM) for 8PSK for several Rician parameters K and effective signal-to-noise ratio in the carrier tracking loop α . Thus, our results will reflect the degradations both due to the effects of the fading on the amplitude of the received signal and of a noisy carrier reference.
